A length of a head insertion portion (39) in the left-right direction is a first distance (A1). An area whose length in the left-right direction is the same as the first distance (A1) and which extends in the front-rear direction of a tape cassette (30) is a first area (331). A distance from a right end of the head insertion portion (39) to a right end of the tape cassette (30) is a second distance (A2). A distance from a left end of the tape cassette (30) to a left end of the head insertion portion (39) is a third distance (A3). Winding centers of a first tape support hole (65) and of a take-up support hole (68) are positioned in the first area (331). The first distance (A1) is formed larger than the second distance (A2). The first distance (A1) is larger than the third distance (A3). A center of gravity of the tape cassette (30) is positioned within a range of the first area (331). |
